How does R. Yehudah HaNasi side with R. Yosi against R. Meir and Hanina Ish Ono? Rabbi Yehudah HaNasi defends himself, and that leads into a characterization of each of the Tannaim. Plus, a new focus on R. Shimon, and his connection to R. Akiva. Also, in the end, a verbal direction for a shaliach to write a get does work, but should not be done (with explanation why not). Plus, the first mishnah of the new chapter - what happens if the man designating the writing of a get is not in his right mind, so to speak.
